The Centers for Disease Control and Prevention is under increased pressure from epidemiologists to acknowledge mounting evidence regarding the immune-boosting power of recovery from prior COVID-19 infection.

Evidence that recovery from COVID-19 elicits a long-lasting antibody response has mounted over the past two years.

A growing cache of scientific studies has shown that people with prior infections are significantly protected, even more so when combined with vaccination, creating “hybrid immunity.”
